摘要: 使用激光康普顿散射产生的准单色γ射线在上海激光电子伽马源（SLEGS）测量了γ-Tm（γ，n）反应的光中子截面。使用迭代展开方法获得了8.27至14.61 MeV能量范围内的单能截面。将测量的激发函数与IAEA-2019评估、NewSUBARU数据以及TENDL-2019和TENDL-2021库进行了比较。虽然再现了横截面的总体趋势，但在共振区域仍存在明显差异。根据实验结果，提取了$^{169}$Tm的$\gamma$射线强度函数，并将其与TALYS计算结果进行了比较。
使用实验约束的强度函数，进一步得到了逆$^{168}$Tm（$n，\gamma$）$^{169}$Tm反应截面计算，为核反应模型和评估的核数据库提供有用的约束。
